Opera 11 offers beefed up security, new features

Opera Software has pushed out Opera 11, touting some new features to enhance browsing experience for users, and some security enhancements to protect them.

Opera 11 has been released to the general public as a free web browsing solution. It's most touted new feature is "tab stacking", which essentially allows users to group similar tabs together to reduce clutter and better utilize on-screen workspace.

Opera has also gotten support for extensions, an area where it has lagged far behind its rivals in the area. Enhancements made to Opera's under-the-hood security features, geolocation features and its support of HTML 5 bring the browser in line with rival Desktop browsers.

It has an estimated share of the overall market of between 2 and 3 percent, but its success has come with mobile devices and games consoles, being the only available browser on Nintendo's Wii and handheld DS consoles.
